Abstract
An LED street lamp including a PLC modem and a control circuit is disclosed. The LED street lamp is able to receive control commands from remote controller. It is also capable of doing self-control based on status information gathered by diagnostic circuit. A system for LED street lamp monitoring and control is also disclosed which includes a central controller, a distribution network and a plurality of LED street lamps. Based on the PLC technology, each LED street lamp can be centrally controlled by the central controller.
